SPECIFICATION forming part of Letters Patent No. 248,160, dated October 11, 1881.

.To all whom it may concern:

Be it known that I, URBAN GoTzENBRtie- GER, a citizen of Austria, residing at Vienna, Austria, have'invented new and useful Improvements in Apparatus for the odorless Emptying of Sinks, Sewers, &c., of which the following is a specification.

This invention relates to apparatus for the odorless emptying ot sinks, oesspools, &c.; and my invention consists in the combinatioinwith an oven for burning the foul gases,which oven is furnished with an inlet and an .outlet pipe, the latter movably mounted on the top of the even, of a double-acting air-pump provided with a reversing-cock, a three-crank shaft, two of which are connected with treadle's and the other to the piston-rod, and a fly-wheel provided with a balance-weight, said members being mounted upon a wheeled frame, all as more fully hereinafter described in detail.

The apparatus will be fully described in detail, and the improvements afterward pointed out specifically in the claim.

This invention is illustrated in theaccompanying drawings, in which Figure 1 represents a side elevation of the apparatus without the transport tank or vessel. Fig. 2 is a plan of the same without the tank, also leaving away the reversing-cock on top of the cylinder. Fig. 3 is aside elevation of the reversing-cock, partly broken through to show the interior. Fig. 4 is a side elevation of the transport-tank. Fig. 5 is a cross-section through the pump-cylinder, also showing valve-channels. Fig. 6 is the gate-valve of transport-vessel, ((letails.)

The apparatus is constructed as follows:

By the legs a a a pump-cylinder, A, is fastened upon a frame, G, Figs. 1 and 2. In front of the cylinder and on the same-level a crankshaft, E, is jourualed in bearings 6, also tastened upon the frame G. On this shaft a flywheel, L, with balanee-weight l, is fastened. The shaft has three cranks, two of which, H and H stand at an angle of ninety degrees to each other, and so to the third one connected to the piston-rod that neither two of the deadcenters of the three can occur at the same provided with pedals k and 70*. On their other Application filed May 26, 1881. (No model.) Patented in Austria October .20, 1880.

ends these treadles are pivoted in hangers k fastened to the rear end of frame Gr. Besides these there are guides 70, fastened on both sides of the frame G, to prevent any lateral motion of the treadles. mounted on frame G, to which the men working the pump may hold on to steady themselves.

Just in front of the fly-whcel stands, upon legs 1', the oven R, on the top of which an elbow-pipe, W, is fastened by coupling so that it may be turned in any direction to conduct away the smoke and hot air issuing from the stove It without annoying the men working the pump. By connecting another pipe or hose, 1*, to r the hot air may be led away to be used for thawing out frozen parts, or for similar purposes.

The pump-crank of shaft E is connected to a double (frame) rod, 1), with journal (1 This connecting-rod D encompasses the cylinder, and is on its other end, by crossbar d and bearings (1 connected with piston-rod O, as shown in Figs. 1 and 2.

Between the two bearings 61 a cross-bar, (1, turns a roller, d which serves to guide the connecting-rod. This is done alternately on top or bottom upon two guide-blocks, F, fastened to frame Gin the manner and position showniu Fig. 1.

A post, Z, with cross-bars, is"

The valves of the cylinder are arranged as I follows: The entrance and escape of the air into and from the cylinder is regulated by four ball-valves, m m m on, only two of which operate at a time-one for suction, the other for From the valves there are channels 1 pressure. leading, into the cylinder and into ports 0 0 respectively. These ports are provided with flanges, ontowhich the reversing-cock is fastened. In this manner always two valves cor respond with pipe 0, and two, with pipe 0?. These two pipes converge into the box of a cock having five ports, two of which lead to the two pipes 0 0 the third to pipe Q, leading to the transport-vessel P, the fourth into pipe S, leading to the even, while the fifth communicates with the outside air. Into this boxfits a plug, provided with four ports or apertures, which correspond with four of the ports in the box, while the fifth of the latter is closed by the web of the plug.

A vacuum-gage, B, and a pressure-gage, M, are placed upon pipes 0 and 0*, for the purposes before mentioned.

Vhen a vacuum is to be created in transport vessel or tank P the cock is turned so that the port of the box communicating with the outside air is shut, while pipe Q, communicates with pipe 0 and S with 0. In the drawings this position is shown in Fig. 1, with the handle or wrench of the plug turned to the right, (upon S.) \Vhen turned to the other side (marked by D, Fig. 3,) the pipe S is shut oft, and Q communicates with the port leading out into the air. The transport-vessel is a wooden one, barrel-shaped, and provided with bands or hoops, not only on its outside, but on the inside as well, to resist the pressure of the atmosphere when a vacuum is produced in the vessel. Inside, in the upper part of this vessel, a float-valveis placed, so that when the contents reach a certain height the opening into pipe Q, will be closed.

0n the head or end of the transport-vessel is a gate-valve, U, consisting of a box, a and slide a. The latter is provided with a sharp cutting-edge on its lowerside, soit will on being closed out its way through any obstacles which might be in the valve. On the topof this slide is fastened a rod,u passing through a stufiingbox in the cover a of the valve. This rod is lnovably connected with a lever. u, turning upon pivot a Lever a also has an extensionpiece, a hinged to it, which can be turned'back when not in use. From the valve projects outward a short tube or nipple, u forming part of a pipe or hose coupling.

The apparatus is put in motion byone or two workmen operating the treadles K K and works in the following manner: Supposingthe crank-shaft standing in the position shown in the drawings, Fig. 1, the balance-weight ot' the fiy-wheel will be down in its lowest position. Now, when the man working treadle K presses it down he imparts to crank H a downward motion, and moving the flywheel raises the balance-weigh t. Before crank H has reached its lower dead-center crank 11 of the other workman has passed over its upper dead-center, and before it reaches its lower one the balance-weight has arrived at its highest point, and sinking down on the other side now helps the piston on its way back, at the same time lifting the trcadles again as they come down. The working of the pump is as follows: When the cock stands in the position shown in Fig. 1, (the handle upon 8,) the piston moving from right to left, air is drawn into the cylinder at m, Fig. 2, and expelled again at m, while at and m remain closed. On the piston going back, at is suction and at pressure valve. In

the first motion airis drawn from the vessel P, and takes the course indicated by dots and arrows from pipe Q, at 0 through the cock into the pipe 0 from there to m and entering at 1, Fig. 5, raises ball m and enters through II into the empty space of the cylinder. The air in the cylinder to the left of the piston is driven through valve m (at III and 1V, Fig. 5) into pipe 0 Fig. 1, and from there through the cock into pipe 0, and through pipe S into the oven, where it is purified and led ofi' into the open air through pipe r By the return-stroke of the piston air is also drawn from "essel 1?, but now it enters the cylinder at m, and is expelled at m By removing the air from ves sel P a vacuum is created. When. by means of hose or pipe V and X, the vessel is connected with the sink or cesspool, the contents of the latter will rapidly till the vessel on opening valve U. \Vhen the vessel is full a float-valve in the top of the same closes, and a rapid rising of the vacuum-gage indicates that it is time to stop pumpin When the contents of the vessel P are to be transferred into a railroad-car, for instance, the reversing-cock is turned to the opposite side, (the handle upon D,) and the same action of the pump takes place, but reversedly. Air is drawn from outsideat 0, Fig.3, through pipe 0, into the cylinder, and from there forced through pipeQinto the vessel, driving the contents ot' the latter through a suitable connecting-pipe into the car, while the air escaping from the latter is driven through an escapepipe into the oven and there purified.

I do not here claim the construction of double-acting air-pump herein described, nor the construction of hosecoupling, as such will constitute the subject-matter of separate applications t'or Letters Patent.

\Vhat I claim as new, and desire to secure by Letters Patent, is-- In apparatus for the inodorous emptying of sinks 0r ccsspools, the combination, with an oven for burning the foul gases, said oven pro vided with an inlet and outlet pipe, the latter movably mounted on top of said oven, of a double-acting air-pump provided withareversing-cock, of a three-crank shaft, two of these cranks connected to treadles and the third to the piston-rod, and of a tly-wheel provided with a balance-weight, all of these parts mounted upon a frame resting on wheels.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
